This is an unlikely case, but this is what happened to me. If the voltage/power of what the charger is plugged into is not sufficient enough to charge your computer, the light will be green and/or 'Not Charging' will be displayed in the menu bar. This happened to me on the plane. I use a pretty powerful laptop.

The first thing I would do is an SMC Reset. According to Apple, one of the reasons to reset your SMC is... To do a reset Shut down the Mac. Plug in the MagSafe or USB-C power adapter to a power source and to your Mac. Using the built-in keyboard, press Shift Control Option on the left side of the keyboard, then press the power button at the same time. ...

Your Mac should still be able to turn on with a dead battery. As long as charger is functioning properly, it's more than enough to both power up and charge your Mac. You have three possibilities for the cause of this: MagSafe Board (highest probability). This board is known to go bad and when it fails, it presents symptoms similar to what you are ...

Even if your battery is dead, your computer should still switch on, see this article for more details. Might be power cables inside your laptop. You can test with voltage meters, if you don't know how it works, you can always go to an electrician or just take it into a computer shop or even Apple.

The battery appears to be dead or damaged. I would go to an Apple Store to have it replaced. But It is still strange that even with the power cable connected it does not turn on. Another test you could do is resetting the PRAM by holding Command + Option + P + R and turning on the MacBook

This is normal and the reason to it is so as to prolong the overall life of the battery. You can see more information here.

As per this wikipedia article, Batteries gradually self-discharge even if not connected and delivering current. Li+ rechargeable batteries [like the kind in a MacBook] have a self-discharge rate typically stated by manufacturers to be 1.5-2% per month. Basically, even if you are not charging or discharging your Mac battery at all, it will still ...

You can check what the weight of the MacBook Pro should be from Apple's specifications and compare with the current weight of your machine. If it turns out that your machine is heavier, you can then do something about it.

The battery indicator for headsets does not appear on the Mac, regardless.

This should be absolutely fine. I haven't tried it myself (yet) but Apple themselves state that you can use the 29W adaptor with the 12.9" iPad Pro, and other people have verified that it works (and doesn't cause damage). This all came out before the 9.7" iPad Pro was released, and it doesn't look like Apple have updated the product page for their USB-C to ...

It's probable that your adaptor is wet. The Gold-coated pins actually move toward the inside of the tip of the cable where that green led is. If you can find a way to blow inside that tip while pressing on the pins, tucking them in, you can by one chance dry it and get it working again.

It's not possible to schedule Airplane Mode unless you have a jailbroken device. If you want to jailbreak your iPhone, there's a few apps that do this exact thing. This sounds like it would be a good idea so I recommend you let Apple know you want this on their iPhone Feedback page.

There is a small glitch here. Its true that the Macbook will stop charging the battery once 100% is reached and will power directly from the adapter if it is plugged in. But what damages the battery in this condition is the heat. Battery is a chemical device and when left under heat with 100% charge will change the chemical properties of the materials used ...

You can find this information along with much other battery and/or system information from the command ioreg This command, according to its man page, does: ioreg displays the I/O Kit registry.

Yes, you are going about this the right way to determine your battery's remaining capacity and life. When a battery reaches over 1000 charge cycles, it is considered "consumed", aka it's lived out the expected life cycle and any degradation in capacity is totally expected. This is never covered by warranty. A consumed battery may still hold some charge, ...

There's nothing significant that could cause your Late 2011 MBP to swell in that area. In fact, that area has a fan mounted there, which makes it quite unlikely that something could get hot enough to cause frame damage. My speculation: If you've had swelling in the past then your frame is probably still bent from the swelling of the first battery. The ...

You should only use the battery that's for your phone. The phone is not meant to take a higher wattage battery, so it will malfunction. To put that into context, it's like trying to put a V8 engine into a hairdryer. It won't work.
